| Abstract: | Two coordination compounds of palladium(II) with N-allylimidazole (l) of the general formula PdL4]Cl2 · 3H2O (1) and trans-PdL2Cl2] (2) have been synthesized. The crystal and molecular structure of complexes 1 and 2 was established by single-crystal X-ray diffraction analysis. The X-ray structural data were supplemented by solid-state 13C NMR measurements (CP MAS and PASS 2D). The 1D and 2D NMR studies in solution reveal that complex 1 is unstable at room temperature and undergoes reversible decomposition to 2. The method for how to preserve a complex with four allyl-imidazole ligands in solution is shown. |
